Lo Guys,
Went to use my water filler cap on the westy for the first time and it came off in my hand

Looks like the cap has come off with the locking ring inside the fitting. Is it a case of superglueing the locking ring in the fitting? I will try and take some pics when the rain stops to avoid confusion

Just a bit worried that it will drop off on our journey. Gunzl do them but don't think they will be able to get it to me in four days!
Take care,
Jamie
